Rockwood, North Muskegon, Robert Torresen and Anthony J. Gretzky, Muskegon, and Milton E. Brown, deceased, late of Grand Haven, by Burvelle E. Brown, administrator, Grand Haven, Mich., assignors to Brunswick Corporation, a corporation of Delaware Filed July 9, 1963, Ser. No. 293,909 11 Claims. (Cl. 273-43) This invention relates to bowling pin handling apparatus, and particularly to a pin handling mechanism for use in an automatic pinsetter to enable the selective setting of less than the normal complement of ten pins for practice bowling, for example.

It it a general object of the invention to provide a new and improved pin handling apparatus of the type described.

Another object is to provide a new and improved pin handling apparatus of the type described, including an indexable pin receiving turret for delivering pins to a pin setting deck structure, conveyor means having a discharge end disposed to deliver pins successively to pin receiving pockets in the turret, means for operating the conveyor and the turret in timed relationship to fill the turret pockets, and selectively operable means for controlling the turret and the conveyor means to fill only preselected pockets in the turret less than the total number of turret pockets,

A more specific object is to provide a new and improved apparatus of the type described, including manually selectively operable control switch means corresponding respectively to pin receiving pockets in the turret, for controlling operation of the conveyor means and turret to preselectively prevent delivery of pins to preselected turret pockets.

Still another object is to provide a new and useful apparatus of the type described which is capable of functioning during normal two-ball bowling in setting the normal complement of ten pins but which is also usable for setting preselected combinations of pins for practice bowling purposes, e.g. for one-ball bowling against preselected spare combination, wherein the pinsetter can be signalled to automatically reset the same pin combination after each ball or alternatively can be signalled to set a new combination of pins as selected after each ball.

Yet another object is to provide a bowling pin handling apparatus which includes a pin conveyor and delivery means for feeding pins to an indexable pin receiver including a plurality of pin receptacles arranged to move successively past a pin receiving station in such a manner that pins are delivered only to preselected pin receptacles and the indexable receiver is otherwise maintained empty, and in which apparatus there is also included deck means disposed to receive the pins from the preselected receptacles and deliver the pins so received to a bowling alley, especially while maintaining the deck structure otherwise normally full of pins so that the deck structure normally contains a full complement of ten pins to enable more rapid and efiicient change in pin selection.

In preferred aspects of this invention, features which may be employed in accordance herewith are motor actuated cable operated single clamp means for preventing setting of non-selected pins by'the deck structure, a turret control system including a wiper adapted to track on a plurality of concentric circular arrays of contacts for completion of electrical contact at or during appropriate intervals coordinated with the rotation of the turret to effect control of delivery of pins to the turret, a console device removed from the location of the pinsetter for remote actuation of control means at the pinsetter, an accessible means such as a jumper arrangement on the pinsetter in a disconnect plug of the control console adapted to prevent pin jams if the console is unplugged while the turret is receiving pins, a particular cable control assembly which includes a motor adapted to drive a threaded shaft to cause a nut member to thread longitudinally on the shaft and tighten a cable for holding clamps in the pin deck in a preselected position to permit or prohibit setting of pins from the pin positions as desired wherein the movement of the nut along the shaft and the movement of the pin deck structure during the pin setting operation are effective to automatically hold the proper clamps in proper positions and are also effective to reset the cable control mechanism responsive to conditions at the pin deck for use during a subsequent pin setting cycle.

Other objects and advantages will become readily apparent from the following detailed description taken in connection with the accompanying drawings, in which:

While an illustrative embodiment of the invention is shown in the drawings and will be described in detail herein, the invention is susceptible of embodiment in many different forms and it should be understood that the present disclosure is to be considered as an exemplifioation of the principles of the present invention and is not intended to limit the invention to the embodiment illustrated. The scope of the invention will be pointed out in the appended claims.

The present invention is best understood with the disclosure of A. P. Rogers, US. 3,219,345, issued Nov. 23,

1965, and especially the portion of the disclosure relating to Rogers FIGS. 1 through 7, as background. That disclosure is incorporated herein by reference. Rogers discloses a pin handling mechanism for use in an automatic pinsetter and including a turret structure and a conveyor structure arranged to deliver pins one at a time to the turret structure. The conveyor is adapted to receive pins from a pin gathering mechanism for collecting pins in the pit at the end of a bowling alley, elevating the pins to the level of the receiving end of the conveyor and depositing the pins on the conveyor for travel serially with the butts of the pins leading. The turret structure is adapted to deliver as many as a full complement of ten pins to a pinsetting structure for setting the pins initially in playing position on the alley, lifting standing pins after a first ball is rolled in order to permit removal of dead wood, and resetting such pins in playing position for the second ball. A complete automatic pinsetter is not described and illustrated herein, but rather reference should be made to such known pinsetter as that described and illustrated by Huck et al. in US. 2,949,300, patented Aug. 16, 1960 as a pinsetter in which the apparatus herein described can conveniently be used.

According to the present invention, a control is imposed on the mechanism described by Rogers with reference to Rogers FIGS. 1 through 7 and 13 through 15 for the purpose of preselectively designating only one or more pin positions, less than ten, at which it is desired that pins be set. Such a control enables the setting of a selected pin, or a group of selected pins, rather than the entire complement of ten pins, for example, for the purpose of enabling a bowler to practice shots at selected pins. To assist in correlating with that system and imposing the control thereon, the reference numbers used in this application are identical with those used by Rogers, and FIGURES 1 through 16 of this application are the same as FIGS. 8-10, 100, and 11-22 seriatim of Rogers. Thus, for any elements illustrated and referenced in the present drawings and not particularly described herein, those in the art can readily refer to the Rogers patent for the more complete description.

Referring now to FIGURE 1, a pin gate and turret control solenoid assembly is provided as generally shown at 200 mounted by bracket 200a to frame member 14. The solenoid assembly has two solenoids -12 and S-13 secured therein, each of which may be a 230 volt A.C. solenoid. Solenoid S-12 is provided for causing the pin receiving turret to index any or all of the nine outer pin receiving pockets past the pin receiving station while at the same time preventing delivery of pins from the cross conveyor to the selected pocket or pockets which are not to receive pins. Thus, solenoid S-12, when energized, indexes the turret in the same manner a-s a pin dropping on the turret indexing lever 99 would index the turret. Solenoid 5-13 is provided for causing the turret to index the chute 35 past the #5 pin receiving station while preventing delivery of a pin from the cross conveyor when the #5 pin has not been selected. Additionally, solenoid 5-13 trips the turret-spider latch to drop pins from the turret to the deck when the #5 pin has not been selected.

Solenoid S-12 slidably operates link 201 which is pivotally connected to lever 99 as at 203. Thus, lever 99' is pivotable by link 201 about its mounting on the frame, as at 100. As described by Rogers, clockwise movement of the trip member 99 in this fashion is effective through the latch release link 95 (FIGURE 1) to pivot the latch 90 in a clockwise direction, releasing the stop roller 83 and the stop lever 84 to free the turret for indexing rotation. It will be understood that the solenoid mechanism thus described produces the indexing function normally provided by the dropping of a pin from the cross conveyor onto the trip member 99. The latter is returned to its normal position illustrated in FIGURE 1 by the spring mechanism 102.

Solenoid S-13, slidably operates link 202 which is pivotally connected to lever 206 as shown at 204. Lever 206 is spring urged in a counter-clockwise direction from the position shown by torsion spring 209 and carries cam roller 208 at its other end. The function of cam roller 208 is to ride an inclined cam surface 220 on a member 221 pivoted on the turret assembly, upon rotation of the turret to bring cam 220 into contact with roller 208. The upward urging of cam 220 and member 221 causes lever 111 to pivot about its mounting at 112 to the left as viewed in FIGURE 1, lever 111 and member 221 being yieldably connected by spring 222. Pivoting of lever 111 causes pivoting of trip member 47 in a clockwise direction as viewed in FIGURE 1 to simulate pivotal movement normally given to this member upon passage of a pin from the cross conveyor 11 to the chute 35. This action frees the spider for indexing movement relative to the turret so that the pins which are delivered to the turret may be suitably dropped to the deck structure therebelow even though no pin is received by the chute 35. Indexing of the spider in the manner described immediately above initiates a series of operations described by Rogers, which results in subsequently indexing the turrent relative to the spider to reposition the spider arms in supporting positions and to index the #9 pocket of the turret to the pin receiving station beneath the end of the cross conveyor 11.

As has been stated, solenoids 8-12 and 8-13 each ad ditionally act to block pin gate 55 and hold the pin gate in closed position to prohibit passage of pins from cross conveyor 11 to the turret mechanism. Accordingly, sleeve member 211 is pivotally mounted on frame member and carries arms 212 and 213 projecting therefrom. Energization of solenoid 8-12 has been described as causing clockwise pivoting of trip member 99. Upon clockwise pivoting, an arm 207 on trip member 99 engages arm 212 upon which a pin gate lock link 2114 is mounted. Pin gate lock link 2114 is connected pivotally to the pin gate arm 57 as shown at 215 for locking the pin gate 55 in its closed position shown in FIGURE 1 regardless of release by latch member 64.

For locking of the pin gate by solenoid S-13, arm 213 is engageable by an abutment lever 206 which is moved in clockwise direction by the action of solenoid S-13 as already explained. Lever 206 acts by engagement with arm 213 through sleeve 211, arm 212, pin gate lock link 214 and pivotal connection 215 to hold pin gate 55 in raised or closed position regardless of the operation of latch member 64.

Because of the normal timing of pin gate 55 with usual operation of the illustrated embodiment, the pin intended for chute 36 is normally conveyed past the pin gate 55 before chute 36 is completely indexed to receive the pin. For this reason, solenoid 5-13 is energized, in a manner to be more fully descirbed hereinbelow, just prior to indexing of the chute to the pin receiving station beneath the end of cross conveyor 11. In this manner, the pin intended for chute 36 is timely stopped on the cross conveyor when no pin is needed in the 45 pin position. Thus, with 8-13 energized as the turret rotates to position chute 36 beneath the end of cross conveyor 11, cam 220 contacts roller 208 and rides upwardly on the roller in such manner that upon proper positioning of chute 36 lever 111 is urged to a raised position pivoting trip member 47 in a clockwise position and triggering the same mechanisms as are triggered by dropping a pin through chute 35 for dropping pins delivered to the turret to the deck structure below the turret even though chute 35 receives no pin.

Also shown in FIGURE 1 is solenoid S-14 which may be termed a stop solenoid, a control superimposed on normal pinsetter operation for purposes of providing one of two alternative modes of operation utilizing the control of the present invention. As will appear, the solenoid may be utilized selectively to provide, instead of automatic operation whereby selected pins are repeatedly positioned on the alley, a mode of operation whereby the pattern of selected pins may be frequently changed. Specifically, as will appear, the solenoid is provided to stop the pinsetter, after each ball is rolled, at 180 in its cycle, that is, with the rake mechanism down adjacent the alley in its most rearward position having just swept pins, to remind the bowler that a pin selection I should be made and the pinsetter set in operation.

As indicated above, the present apparatus is intended for use with and as part of automatic pinsetters such as that described by Huck et al. in US. 2,949,300. As illustrated in FIGURE 1, solenoid S-14 is mounted to a suitable frame member 14 by means of a mounting bracket as indicated generally at 131. The operating or motor arm of solenoid S14 is secured by bracket 130 to a connecting link 236. The connecting link 236 corresponds to the connecting link 236 of Huck et al., cited above, which acts to control a clutch assembly and the upper deck position to effect the 180 stop. The stopping action and the mechanisms particularly effecting the 180 stop are fully described by the Huck et al. patent and reference is made to that patent for fuller explanation thereof.

Mounted above the turret is a control box 140 for solenoids 8-12 and 8-13. Control box 140 is mounted on a supporting bar 151 secured to frame member 51 by means of support bracket 152. The box is also supported by means of brackets 14-5 on frame member 143. A flexible drive shaft 147 is suitably connected at 33 to the turret for rotation therewith, preferably at about the axis of rotation of the turret. Flexible drive shaft 147 extends into control box 140 and drives wiper 160 counterclockwise about circular arrays of switch contacts, TS-1 through TS12, as better illustrated in FIGURE 3. Wiper 160 has been shown removed from the switch contacts for clarity and is illustrated in FIGURE 4 but its association with the arrays of contacts will be apparent.

Wiper 160 (FIGURE 4) includes a fiat driven member 161 having an arm 162 carrying inter-connected electrical wipers or contact members 163, 164 and 165. The three wipers are adapted to wipe the three concentrically circular arrays of contacts on the printed circuit board 166. Wiper 163 is the common wiper which slides over circular contact 167 while Wipers 164 and 165 slide over the inner and outer circular arrays of contacts in the order of their positions upon the board 166 to in effect close switches TSI through TS12. The complete circuitry will be apparent with respect to the wiring diagram of FIGURE 16 discussed hereinbelow.

A time delay 168 and first and second rake switches 169 and 170 are also mounted within the control box as shown in FIGURE 3. The function of the time delay will be described below. Rake switch 169 is a normally open switch and rake switch 170 is a normally closed switch. Switches 169 and 170 each include a pivotally mounted switch operating arm 142a spring biased in a counter-clockwise. direction to hold switches 169 and 178 in their normal positions. Switch actuator 142C, mounted by bracket 142 to rake shaft 141 for movement therewith, is adapted to pivot operating arm 142a against the biasing of its spring to actuate switches 1 69 and 170 respectively to closed and open positions (as shown in FIGURE 1) upon counter-clockwise rotation of rake shaft 141 for the purpose of returning the rake to its normal retracted position. Clockwise rotation of rake shaft 141 to sweep the alley results in release of operating arm 142a permitting return of switches 1619 and 170 to normal positions. The rake switches are used for control purposes which will be more apparent hereinbelow.

Referring to FIGURE 5, in order to hold a pinsetter of the type illustrated in the previously mentioned Huck et al. Patent 2,949,300 at all times during selective pin bowling in a mode of operation corresponding to that normally following the second ball in conventional bowling, the pinsetter may be provided with a solenoid 8-11 connected as by a link 171 to an extension 494 of a latch 492, corresponding respectively to the extension 494 and the latch 492 in the patent mentioned, to move the latch in a clockwise direction from the position illustrated in FIGURE 5 to a position providing second ball operation in the manner set forth in the patent. This assures that during selective pin bowling, after each ball is rolled the selective pin setup is again repeated without the need for the pinsetter to go through cycling normally providing for the rolling of two balls if these are necessary to knock down the pins. As will appear, the solenoid 8-11 is connected in the circuit of FIGURE 16.

Turning now to FIGURES 6-9 of the drawings, there is illustrated an automatic pinsetter deck structure of the general type disclosed in U.S. Patent No. 2,949,300 to Huck et al., and reference may be had thereto for additional discussion of the pinsetter construction and operation. The deck structure is substantially horizontally disposed over the end of a bowling alley adjacent its pit for receiving pins from the turret and setting the pins on the bowling alley in preparation for bowling. In normal bowling operation of the deck structure for conventional bowling, after a first ball has been rolled, the deck structure picks up the pins which remain standing to permit removal of dead wood and then resets the last mentioned standing pins for continued bowling and normally after each frame the pinsetter sets new pins on the bowling alley for play of the following frame.

Generally, the deck structure is vertically movable toward and away from the surface of the bowling alley over which it is installed. The pinsetter deck structure includes an upper deck 225 having a generally triangularly shaped upper deck plate 227, and a lower deck structure 228 including a generally triangular-1y shaped intermediate deck frame or plate 229a and a lower triangular deck plate 22%. As illustrated in FIGURES 8 and 9, upper deck 225 is supported on lower deck 228 for movement longitudinally of the bowling alley by tracks 231 on the upper deck riding on rollers 232 journaled on shafts 233 mounted on the lower deck. Upper deck plate 227 has suitable openings 234 for receiving bowling pins from the turret. Pins delivered to openings 234 are received on suitable rollers 235 mounted on lower deck 228 when upper deck 225 is disposed longitudinally forwardly on lower deck 228 in a pin receiving position. By moving upper deck 225 longitudinally rearwardly on lower deck 228 to a pin setting position (not shown), the upper deck plate openings 30 are generally aligned with and overlie pin passing openings in the lower deck plates 229a and 22917 and pins in upper deck openings 234 move off of lower deck rollers 235 and drop through the lower deck openings.

Mechanism for moving upper deck 225 across lower deck 228 is fully described in the aforementioned Huck patent, and will be briefly described herein in the form of a cable mechanism. Movement of the upper deck 225 forwardly on lower deck 228, from the pin setting position (not shown) to the pin receiving position illustrated in FIGURES 6 and 7 is accomplished by drawing a cable 230 over a pulley 230a journaled on the upper end of a support 237 which is mounted on lower deck 228. Cable 2 30 also passes around a pulley 238 journaled on lower deck 228, and passes around and is attached to a pulley 239 secured to the end of a shaft 240 for rotating pulley 239. Shaft 240 extends across the rear of lower deck 228 and is journaled at opposite ends on the lower deck. Secured to pulley wheel 239 are a pair of generally diametrically opposed outwardly extending cam pins 241a and 24111 which are movable in cam slots 242a and 242b, respectively, in cam plates 2420 secured to and depending from both sides of upper deck 225, for moving the upper deck forwardly and rearwardly on lower deck 228. During movement of the upper deck to the pin receiving position shown in FIGURES 6 and 7, pulley wheel 239 is rotated clockwise as seen in FIGURE 7, winding a spiral torsion spring 244 which is telescoped on shaft 240 and has one end 244a a-nchored on lower deck 228 and an opposite end 244b attached to a spring anchor secured on shaft 240. When cable 230 is released spring 244 partially unwinds, rotating pulley wheel 239 counter-clockwise and cam pin 241a upwardly in slot 242a rapidly moving the upper deck 225 rearwardly on lower deck 228, whereupon cam pin 2 41b is engaged in cam slot 242b continuing rapid rearward movement of the upper deck. Actuation of cable 230 is controlled in a suitable manner responsive to a pinsetter operating mechanism as is f-ully discussed in the previously mentioned Huck patent.

Mechanism is provided for lifting and resetting standing pins on the alley for removal of dead wood after the first ball of each frame during normal bowling. In the illustrated embodiment upper deck 225 is provided on its underside with circular resilient pads or discs (not shown) suitably secured to the underside of upper deck plate 227 and positioned to engage pins standing on the alley when the deck assembly is lowered and in pin detecting position, whether the pins are standing exactly on spot or within a predetermined area surrounding the spot. Engagement of the pads with the tops of standing pins holds the pins securely in position to be gripped at the neck thereof by scissor pick-up mechanisms 243, one associated with each opening in the lower deck and mounted on lower deck plate 22% for securely gripping a pin standing within the opening. Suitable scissor pick-up mechanism is more fully discussed in both the aforementioned Huck patent and in Sanford Patent No. 2,817,528.

Also for normal bowling, means for detecting and indicating pins standing on the alley may be provided by apparatus including switch assemblies 245 mounted on upper deck plate 227, and one associated with each opening 234 therein. Each switch assembly is operated in repsonse to a switch actuator detecting the presence of a standing pin on the bowling alley surface to operate a suitable indicator visible to the players, such as a light illuminated in response to operation of the respective switch assembly 245, as is more fully described in copending patent application of Conklin and Torresen, for a Pin Detecting and Indicating Apparatus, SN. 126,974, filed July 26, 1961, and now Patent No. 3,118,671.

In association with switch assemblies 245, four cables indicated by reference numeral 246 extend diagonally across the top of upper deck 225 and each cable operates one or more of switch assemblies 245 to reset the latter. The cables 246 are guided by pulleys mounted for rotation about vertical axes, and each cable has an end suitably secured to a fitting pivotally attached as by bolt to one arm 2470 of a bell crank 247. The bell crank is suitably journaled by a nut and bolt assembly on a housing 227a on upper deck plate 227 for pivotal movement about a vertical axis. During movement of the deck assembly from pin detecting position as shown in FIGURE 12 to pin setting position (not shown) upper deck 225 moves longitudinally of the bowling alley and rearwardly across lower deck 228. A second arm 24717 of the bell crank engages an abutment 228a on the lower deck assembly 228 and the bell crank moves clockwise as viewed in FIGURE 12. Such clockwise movement of the bell crank permits limited movement of the cables 246 with respect to upper deck 225 due to springs provided for this purpose as described by Torresen et al. in copending patent application for a Pin Detecting and Indicating Apparatus, SN. 133,476, filed Aug. 23, 1961, and now Patent No. 3,094,326. The spring retain cables 246 taut. When the deck assembly again moves from pin setting to pin detecting position, the springs also maintain cables 246 tight and bell crank 247 is rotated counter-clockwise through engagement with abutment 228a to prevent any slack developing in the cables 246.

The deck structure as illustrated in FIGURES 6-9 is provided with means for clamping nonselected pins with the deck structure during the pin setting operation where it is desired to bowl only at selected pins. Reference is also made to FIGURE 10. Each pin position is provided with a clamp assembly adjacent openings 234 and adapted to pivot a clamp 295 into the opening to hold a bowling pin against being deposited upon the alley during the pin setting phase. The clamps can be activated or de-activated in accordance with a preselected plan.

Each clamp assembly includes a clamp lever 294 (294b in the case of the clamp assembly at the #1 position) pivotally mounted through a mounting plate 293 and the upper deck 225. A clamp 295 is secured to the lower end of each clamp lever and is carried thereby just below the upper deck 225 for pivoting with the clamp lever. In positions #2 through #10, a cable pulley 296 is rotatably mounted on arm 294a of clamp lever 294. The lever arm of clamp lever 2941) is indicated at 299 but carries no pulley. Solenoids SI through S10, which are spring return solenoids, are mounted on the mounting plates 293 at the respective pin positions, i.e., 5-1. at #1 pin position, S2 at #2 pin position, etc. Solenoids S2 through S49 have their .plungers pivotally connected to latch levers 297 and solenoid S-I has its motor arm pivotally connected to a latch lever 297a. Clamp levers 294 are each urged by a tension spring 298 or a compression spring 298a (#1 position) acting upon clamp lever arms 29% or 299 to bias clamps 295 away from pin clamping position, i.e., away from or out of openings 234. Latch levers 297 engage clamp levers 294 to stop movement of clamps 295 into openings 234, i.e., into pin engaging position.

Cable 256 extends from a cable drive mechanism indicated generally at 248 operatively through a plurality of rotatably mounted cable pulleys, including the aforementioned cable pulleys 296, and its other end is anchored on lever 299 at 309. The additional pulleys other than pulleys 296 are indicated in FIGURE 6 and may be referred to herein as pulleys 301, each of .which is mounted for rotation on one of the pulley mounting plates 392. The pulley mounting plates 392 are secured in raised position above the upper deck.

In operation, preselection of a pin position for setting only selected pins, by means to be fully described hereinbelow, results in preventing completion of an electrical circuit to the solenoid controlling the clamp lever latch at the positions selected. During the pin setting phase when the pins are being deposited on the bowling alley, an electrical circuit to only the solenoids at the nonselected positions will be completed just prior to relative movement of the upper and lower decks for depositing the pins on the bowling alley. Thus, the solenoids at the nonselected positions, being energized will pivot the latch levers 297 out of engagement with clamp levers 294 to enable the clamp levers to be pivoted clockwise against the urging of tension springs 298. At the selected positions, latch levers 297 will prevent such clockwise pivoting of the clamp levers. In the case of pin position #1, where the pin position is not selected, solenoid 5-1 will be energized and will pivot latch lever 297a in a counter-clockwise direction to permit counter-clockwise movement of lever arm 299 which is otherwise blocked from appreciable counter-clockwise movement by latch lever 297a. Pivoting of lever 299 is against the urging of compression spring 298a. If pin position #1 is a selected position, solenoid S]l Will not be energized and the lever arm will be blocked.

Also prior to shifting of the upper and lower decks for setting of the pins, cable 256 is pulled by cable drive 248 in a manner to be discussed below. It will be noted that cable 256 operatively engages pulleys 296 from one side of clamp lever arms 294a in such manner as to urge the clamp lever arms against the latch levers when the solenoids are de-activated. In those pin positions where the solenoid is activated and the latch lever is pivoted out of engagement with the clamp lever arm, the pulling of cable 256 will, through pulleys 296, pivot the lever arm 294 so as to carry the clamp 295 into engagement with a bowling pin in the opening 234. Such engagement of a pin with the clamp would prevent the bowling pin from passing through opening 234 and from being set on the bowling alley. However, where the solenoid is not energized, due to selection of the pin position, the clamp will not be pivoted to engage the pin and the pin will be permitted to freely pass through the normal pin setting operation to the bowling alley.

In the case of pin position #1, the end of cable 256 is secured to lever 299 and upon pulling cable 256 lever 299 is moved or urged against latch lever 297a where pin position #1 is a selected position and solenoid S-1 is not energized, or will cause pivoting of arm 299 and the clamp 295 into engagement with the pin to prevent setting of the pin where pin position #1 is a nonselected position and the solenoid S-l is accordingly energized. Referring to FIG. 16 there are shown capacitors C-l through C-10, one capacitor across the coils of each of the solenoids S-l thru S10. These capacitors are used to compensate for the voltage drop caused by the current drain of each of the solenoids.

After the selected pins have been set on the alley, cable 256 is released by the cable drive mechanism 248 and all clamps are returned by tension springs 298 or compression spring 298a to their non-pin engaging positions as shown in FIG. 6. The latch levers also return to their illustrated positions.

In preselected bowling during setting of the pins from the pin deck, the clamps holding the pins in the nonselected positions are maintained effective by means of a motor driven cable arrangement indicated in FIGURE 6 generally at 248. Referring to FIGURES 11 and 12, there is provided a frame 249 which is supported on the upper deck 225 and upon which is mounted a plurality of associated elements for controlling cable 256 which extends in association with the deck clamp pulleys 296 as described hereinabove. Accordingly, motor 250 is provided and drives a screw rod 251 rotatably mounted on the frame. Motor 250 is a reversible motor which may be controlled by on-off switch 291 and through reversing switch 290.

The apparatus illustrated in FIGURES 11 and 12 can best be described with reference to its operation. Accordingly, motor 250 is eneregized by means of second rake switch 170 as will be more apparent hereinbelow. Motor 250 rotates screw rod 251 to cause nuts 252, threaded on screw rod 251, to be driven away from the motor, to-

ward an extended position shown in dotted lines. Nut.

252 carries a pulley 253. Clamp cable 256 extends through pulleys 254, 253 and 255 and is anchored at 257 on rod 258 which is biased to the left by spring 259 grounded against frame member 260. As nut 252 progresses away from motor 250, cable 256 is tightened to hold clamps 295 in their selected positions on the upper deck structure. The resulting tension on cable 256 is also applied at 257 to rod 258 to urge rod 258 against the biasing of spring 259. Rod 258 carries a guide pin 258a which guides in slots 261 in frame 249 defining a limit of lengthwise movement of rod 258. As rod 258 is pulled by cable 256, lever 268 which is biased by spring 270 against guide pin 25811 is permitted to contact and open normally closed clamp switch 271. Opening clamp switch 271 results in de-energizing and stopping motor 250.

As lever 268 pivots about point 269 under the urging of spring 270, roller 272 which is carried by lever 268 is withdrawn from engagement with lever 273. Lever 273 is pivot-ally mounted at 273a and is biased by torsion spring 274 in a clockwise direction. Cable 282 extends from slide member 280 through a system of pulleys 283, 284, 285 to crank member 247 (FIGURE 6) and slide member 280 is in effect controlled by crank memher 247 through cable 282. Crank member 247, which is a part of the pin detection assembly as described above and as more particularly described in the above mentioned Patent No. 3,094,326, pivots and the resulting slack in cable 282 is taken up by sliding of slide member 280 under the biasing of tension spring 281 to permit hook end 2731; of lever 273 to slide past an engaging position with lever 286.

The crank member 247 is caused to return to its original position by the upper deck moving forward after deck motion normally used for setting pins.

Upon pivoting of crank member 247 back to its original position, cable 282 pulls slide member 286 back to the position shown in FIGURE 12 against the tension of spring 281. End 273b engages lever 286 and pivots lever 286, mounted pivotally at 269, in a counter-clockwise direction. As lever 286 pivotsit disengages switches 290, a pair of switches, one behind the other adapted to reverse the direction of the motor 250. Pivoting of lever 286 also compresses spring 287 and because lever 286 is in engagement with pin 288,, pivoting of the lever moves pin 288 away from its blocking position with respect to lever 265. Because nut 252 has progressed away from lever 265 on screw 251, lever 265 is now free to pivot in a clockwise direction under the urging of spring 266. Lever 265 thus engages and closes switch 291 to energize motor 250. Motor 250 rotates screw rod 251 in the opposite direction and nut member 252 is returned to its original position. During return of nut member 252 to its original position, it is apparent that the tension on cable 256 is lessened and rod 258 is permitted to return to its initial position under the urging of spring 259, thereby urging lever 268 from engagement with switch 271 to close switch 271. Roller 272 re-engages lever 273 and pivots end 27% out of engagement with lever 286 and lever 286 is urged by spring 287 toward its original position but is stopped from returning to its original position by engagement of pin 288 with lever 265. Upon return of nut member 252 to its original position, lever 265 is pivoted against the urging of spring 266 out of engagement with switch 291 to de-energize motor 251) and out of engagement with pin 288 to permit pin 288 to return to its original position thereby permitting lever 286 to re-engage switch 290. De-energization of motor 250 by switch 291 is accomplished regardless of the closed position of the second rake switch as will be apparent from discussion of the wiring diagram in FIGURE 16 hereinbelow. Thus, the apparatus is reset for use during the next cycle.

The control panel or console is illustrated in FIGURES 13 through 15. Reference is also made to the wiring diagram of FIGURE 16. Turning now to those figures, the console includes a housing 310 mounted on suitable framework as indicated at 316. Housing 310 includes a top panel member 311 which has a decorative upper surface. As viewed from the upper surface (FIGURE 13), the console includes on-off button 312 for operating onolf slide switch 345, a single spare-repeat spare button 313 for operating the automatic slide switch 346, and a warning light 314. The on-off switch is the master switch for energizing the circuitry of the present control system. The automatic switch is turned to the on or repeat spare position for the purpose of repeating the same combination of pins set by the pinsetter with each machine cycle for practice bowling purposes. The warning light or indicator indicates to the bowler when the keyboard is locked and buttons cannot be depressed for purposes of selecting a new combination of pins to be played.

Set button 317 operates set switch 347 (FIGURE 16) when the automatic switch is in the off or electrically closed position. The set switch is depressed by the bowler to clamp the pins and start or initiate loading of the turret. Clear button 315 is provided to clear the keyboard in a manner to be described hereinbelow.

The keyboard portion of the console includes ten keys or buttons 320, differing from each other only by numerical designations of 1 to 10 on their upper faces. Keys or buttons 320 are carried on plungers 321 an are normally urged to an upward position or raised position by means of coil springs 322 anchored on a plate member 340 and biasing buttons 320 upwardly. Each plunger 321 carries a latch member 323 pivotally mounted on the plunger and normally urged by spring 322 toward a latch or hold position. Latch members 323 are each provided with a recess 325. With buttons 320 in the raised position, latch members 323 are retained to the right as viewed in FIGURE 14, against the urging of spring 324 by means of plate member 340. When the button 320 is depressed, notch 325 becomes aligned with plate 340 and latch member 323 is urged to the left with notch 325 engaging the plate to hold the button and plunger in depressed position.

Clear button 315 is provided to permit buttons 320 to return to the raised position. Button 315 is secured to the top of the plunger 331 which is spring biased by spring 332, anchored on plate 340, to a raised position. Roller 333 is rotatably mounted on and carried by plunger 331. Hold plate 341 is provided for coacting with roller 333 upon depression of button 315 for clearing the keyboard. Release plate 341 abuts each of the latch members 323 in the hold position of the latch members. Plate 34-1 is slidable with respect to plate 340 and is spring biased in one direction, e.g., by spring 339. Depression of button 315 causes roller 333, in engagement with cam portion 341a of plate 341 to urge plate 341 against any of the latch members 333 which are in the hold position and against the biasing of springs 324 of such latch members until notch 325 becomes disengaged from cross member 340, at which time spring 322 urges button 320 back to its raised position. Upon release of button 313, spring 339 returns plate 341 t its position providing re-engagement of notches 325 with cross member 3 i as before.

Each of the buttons 320 controls one of switches PS-1 through PS- in accordance with the number on the upper surface of the button. With buttons 320 raised, PS4 through PS-ltl are all closed by contact with printed circuitry on the lower face of circuit board 343. The printed circuit on the lower surface of circuit board 343 corresponds to circuitry diagrarnmed in FIGURE 16. The switch members PS-l through PS10 are mounted to plungers 321 and insulated therefrom by electrical insulating means 323, e.g., a rubber grommet or the like.

Solenoid 8-15 is mounted within housing 310 and is actuatable to move lock plate 342 into engagement with lock recesses 326 and 327 on each of plungers 321 to lock buttons 325 in the depressed and raised positions respectively. Solenoid S15, by means of lock plate 342, also functions to lock button 315 against depression by sliding lock plate 342 into slot 334 of plunger 331. The lock plate 342 is moved to the left as illustrated in FIG- URES l4 and by solenoid S15 in order to effect the looking action. The solenoid S15 which is a 24- volt D.C. solenoid, is energized just before turret loading begins, i.e., at the time the clamp motor is started, and remains energized until after the turret has been loaded and has dropped pins into the deck. Thus, the solenoid 5-15 prevents the bowler from intentionally or unintentionally changing the selection during this period of time in order to insure correct delivery of pins to the turret and from the turret to the deck, to accurately replace the pins dropped from the normally filled deck.

Lock plate 342 has an abutment 342a engageable with an actuator 306a which controls an anti-tease switch 306 to close switch 306 only when the lock plate is in locking position and open switch 306 when the keyboard is unlocked. Switch 306 controls the selection circuitry (FIGURE 16) to prevent energization of the selection circuits when the keyboard is not locked. Because partially depressed keys may prevent closure of the lock plate, the arrangement assures that the selection circuitry is not energized until the keyboard is locked following completion of a selection.

Set switch button 317 is secured to the upper end of plunger 318 and is biased upwardly by spring 319 in the same manner as buttons 320 are biased upwardly. Plunger 318 works set switch 347 (FIGURE 16), included within the printed circuit on board 343 upon which contacts of the same construction as provided for PS-l through PS-10 are adapted to rest while button 317 is in its normal raised position. Thus, switch 347 is a normally closed switch and depressing button 317 opens switch 347 until button 317 is released and the switch contacts re-engage the printed circuit.

The electrical circuitry of the specific embodiment of this invention is diagrammatically illustrated in FIGURE 16. The circuit is supplied by a power source of 230 volts A.C. applied at A and B. A conventional transformer T1, capable of supplying about 24 volts DC. in the secondary is included as illustrated. Additionally, a conventional circuit breaker CE is employed in the secondary of T-1.

The electric circuitry will be further discussed hereinbelow with reference to the cyclic operation of the pinsetter. According to normal operation, the machine is ready for bowling of the first of two balls at 0 of a cycle. The first ball is bowled and triggers the machine. The pin deck descends to detect for standing pins and lifts any pins remaining standing. The bottom of the detecting stroke occurs at and at the deck is raised carrying the lifted pins. Also at 0, the rake starts down, sweeps the dead wood backward and is at its rearmost position at 180. Thus, at 180 of th cycle, the rake is still down and the pins left by the first ball are lifted. Thereafter, the lifted pins are reset and the rake comes up, the bottom of the re-set stroke occurring at 270. The deck rises and is in its raised position at 360.

Assuming that a second ball is to be bowled, the machine over-cycles and stops at 90 instead of stopping at 360 to await the second ball. This over-cycling eliminates the detecting portion of the cycle unnecessary after bowling a second ball thereby cutting down on pin setting time. The deck remains up while over-cycling. The second ball is bowled and triggers the machine. The rake descends and sweeps the alley. The rake is still down at 180 but thereafter rises and a new set of pins is set at 270 by the descending deck and the deck rises at 360 to await the bowling of a new first ball.

Where a strike occurs on bowling the first ball, the absence of pins is detected during the detection stroke and a new set of pins is set at 270 and the machine comes to rest at 360.

The control system for use in the present invention places the pinsetter in a mode of operation at all times simulating that normally followed after bowling a second ball in the frame. Accordingly, the machine always over-cycles and stops at 90, the starting point for oneball spare bowling in accordance herewith. When the ball is then bowled it triggers the machine. In automatic operation for setting the same selective combination of pins in each successive cycle, the cycling continues past 180 and the pins are set as selected at 270 and the deck rises with the machine over-cycling and stopping at 90 to await again the bowling of a ball at the selected pin combination. Where it is desired to change a selection of less than ten pins, this is done before the machine starts from 90. After 90, the turret indexes to receive pins for replacement of the pins in the deck to be set during the next cycle and the pattern for 13 the next cycle set is established. The keyboard remains locked during turret indexing to prohibit making or changing a selection. Thus, if a change in selection is made before bowling, the new selection is set immediately after bowling.

During non-automatic operation, i.e., where it is desired to bowl at different combinations of pins for each successive ball, the new selection of pins is usually made each time the machine is waiting at 90. However, where no selection is made at 90, e.g., the operator forgets to select prior to bowling, the 180 stop solenoid 8-14 is actuated and stops the machine at 180 with the rake still down prior to setting the pins, at which time a selection may be made, and the selected combination is then set.

In initiating either automatic or non-automatic selective operation in accordance herewith, the turret is first cleared of pins so that pins subsequently may be directed only to preselected pockets in the turret. This, of course, entails one cycling of the automatic pinsetter, ordinarily maintained with a full deck and a filling turret, in order to drop the ten pins from the deck and release ten pins from the turrret to the deck to ready the turret for receiving preselected pins. In operation, assuming ten pins are on the alley and the pinsetter is at of its cycle, referring to FIGURES 13-16, in order to ready the pinsetter for operation in selecting a predetermined combination of pins to be set up on the alley deck, the on-oil slide switch 345 is moved to the on position. Relay R-1 is thereby actuated and contacts R1-1 and R1-2 open while contacts R1-3 and R1-4 close. Opening of contacts R1-1 and R1-2 isolates relay R-Z from the anti-tease switch 306. Closing of the R1-3 contacts completes the circuit from time delay 168, a thermal time delay relay with normally closed contacts 168-1, to a pinsetter re-cycle solenoid S-16, in circuit with source C, D. The re-cycle solenoid corresponds to that provided in the pinsetter as shown at 580 in the Huck et al. patent, for example. A delay of about five seconds is provided to cause the pinsetter to cycle once when switch 345 is first closed, and after such delay, contacts 168-1 open. Closing contacts R1-4 energizes the second ball solenoid S-11 located in the pinsetter, so that the pinsetter is over-cycled to 90 for second ball operation thereby to eliminate parts of the cycling nor mally provided for the bowling of two balls.

It will be noted that at this time there is no power to the pin selecting circuitry because the R6-2 contacts and switch 306 are open. When the pinsetter is triggered by the re-cycle solenoid, the ten pins on the alley are swept away and ten pins are set on the alley from the pin deck. At the same time the turret proceeds to load fully.

After the turret has dropped the pins to the deck in the usual manner the pinsetter completes its cycle and stops at 90. As the turret starts to index from the pin position to the #9 pin position with the turret empty, wiper 160 (FIGS. 3 and 4) closes switch TS-11 which makes before switch TS-S breaks and actuates relay R-4 which closes contacts R4-1 and R4-4 and opens contacts R4-2 and R4-3. Contacts R4-2 open. Contacts R4-3 open to disable contacts -R6-2 from energizing the pin selection circuitry. Closing of contacts R4-4 actuates 180 stop solenoid 8-14 for subsequent control to stop the pinsetter at 180 of its cycle unless disabled as explained below.

Immediately after TS-11 is closed, switch TS-12 is made by wiper 160 thereby actuating relay 11-5 to close contacts R5-1, R5-3, R5-4 and RS-S while transferring and closing the normally open contact of R5-2, a single pole, double throw switch. Such actuation of R5-2 disconnects relay R-2 from the negative side of the line and connects the deck solenoids S-1 through 8-10 and relay R-7 to the negative side of the line. Closing of contacts R5-3 actuates relay R-6, thereby closing contacts R6-1, R6-2 and R6-3. Closing of contact R5-4 provides for holding in the 180 stop solenoid S-14 regardless of control by contacts R4-4. Closing contacts RS-S energizes the #5 pin trip solenoid 8-13 to lock the pin gate. Contacts R6-1 close to enable holding of relay R-o through contacts R4-2 (now open). Contacts R6-2 close to ready actuation of solenoid S-15 through .contacts R4-3 (now open). Closure of contacts R6-3 provides a by-pass around on-off switch 345 to prevent deenergizing the selection circuitry by switch 345 during loading of the turret.

The turret continues to rotate to the #9 pin position and switches TS-ll and TS-12 are broken as the wiper travels around the printed circuit in the control box to close TS-Q, bringing the turret to position for awaiting loading. Relay R-4 remains energized by means of contacts R i-l, the set switch 347 and the first rake switch 169, a normally open switch which is held closed while the pinsetter is not cycling, i.e., stopped at Relay R-S is still energized through contacts RS-l and normally closed clamp switch 271.

The pinsetter, being at 90 of the cycle, is now ready for use by a bowler for bowling at a preselected spare arrangement. The bowler makes his selection on the keyboard by depressing buttons 320 as desired and thereafter either rolls a ball at the ten pins on the lane or actuates the re-cycle solenoid by means of a re-cycle button normally provided at the bowling alley in order to get his preselected spare set up on the alley.

For automatic operation wherein the preselected pattern is repeated after each ball is bowled, the automatic switch 346 is turned to the on position to open the switch. As the machine is triggered to set the selected complement of pins, the rake proceeds downward and the first rake switch (closed at 90 of cycle) is opened de-energizing relay R-4. Contacts R4-1 and R4-4 are opened but solenoid 8-14 remains energized by means of contacts R5-4. Contacts R4-2 close to keep relay R-6 energized through contacts -R6-1 while contacts vR445 close to actuate lock plate solenoid 3-15 which in turn locks the keyboard and closes switch 3% to provide power to the selection circuit. Warning light 314 goes on to indicate to the bowler that the selection circuitry is energized and the keyboard is locked.

The second rake switch (held open at 90 of cycle) closes and R-7 is thereby energized to close contacts R7-1 and start clamp motor 250.

All of the pin switches which are not depressed permit current to flow through their respective solenoids which disengage latches permitting clamp motor 250 to clamp all pins which have not been selected. Wherever a pin has been selected, the corresponding PS switch is open and no energization of the corresponding solenoid occurs.

When non-selected pins have been clamped, the clamp switch 21 opens permitting relay R-S to open thereby opening contacts R5-1, R5-3, R5-4 and RS-S while returning R5-2 to its normally closed pole. This results in de-energization of the 180 stop solenoid 8-14 and the #5 pin trip solenoid 8-13. The pin gate is thereby unlocked.

The turret next begins to selectively load in order to replace pins that are being set. As the turret switch is scanned, the wiper passes over and closes TS-9, TS-10, TS-6, TS-3, TS-1, TS-2, TS-4, TS-7 and TS-8 in that order. These segments or contacts are make before break contacts. If a button is depressed, the turret stops and awaits a pin in norm-a1 pin loading manner. If the button is not depressed, relay R-Z is energized through closed TS and PS switches in series which actuates turret index solenoid 8-12 and the turret indexes without receiving a pin. The wiper continues to TS-S, break before make between TS-3 and TS-11, and upon reaching the #5 pin position if the #5 button is depressed, the turret stops and waits for a pin. If the #5 button is 15 not depressed, R-3 is actuated by TS5 and contacts R3-2 close to energize the #5 pin trip solenoid S13 and the spider is thereby tripped to set the selected pins on the alley and energization of the pin causes the selected pins to drop from the turret to the deck. Contacts R3-1 are opened.

Next the turret advances from the #5 to the #9 position and TS-ll is closed actuating relay R-4. R4-2 and 114-3 are opened permitting de-energizing relay R-6 and removing power from the lock solenoid S-15 and selecting circuit and de-energizing relay R-7 to unclamp the pins in the deck. TS-lZ is then made energizing relay R-S. Contacts RS-l and R5-3 close, the latter re-energizing relay R-6. Contacts R5-2 switch to connect relay R-7 and the deck solenoids to the negative side of the line. Contacts R5-4 close. Relay R5 holds in as TS-lZ is broken by progression of the wiper because the deck is now unclamped and clamp switch 271 is in closed position.

The above completes a cycle of operation with the automatic switch 346 closed. Upon bowling a ball, the preselected pins will automatically again be set and the cycle will be repeated each time a ball is bowled.

Where the control circuitry is operated with the automatic switch 34-6 in closed or off position, the cycle is exactly the same except that the set switch 347 must be depressed and opened to cause clamping of the pins and starting of turret loading. If the set switch 347 is not depressed before triggering the machine to move from its 90 waiting position; 'a 180 stop will occur due to solenoid 8-14 being energized and the machine will wait at 180 for the bowler to make a selection and press the set button. If the set button is depressed while the machine is waiting at 90 of cycle, before bowling at the setup then on the lane, the selection having been made at that time, no stop is made at 180. Thus, 180 stop solenoid S44 is used to stop the pin setting machine after 180 of cycle whenever a selection is not on the keyboard, i.e., where a selection of a different combination of pins is to be made between the bowling of each ball and has not been made. It will be recalled that while the pinsetter is at 180 of cycle the rake is down; in non-automatic operation the stop is made at this time so that the bowler will be reminded to make his selection.

Relay R6 has two important functions. As described above, this relay is employed to prevent selective loading of the turret when switch 345 is first turned on. Thus, the turret is allowed to load fully the first time so that a full complement of pins can be maintained in the deck. The second purpose of relay R-6 is to prevent loss of memory from the selection circuitry if switch 345 is turned off while the turret is receiving a pin selection to replace pins set from the deck. If switch 345 is turned off, electrical contact still remains by way of contacts R63 and the cycle will continue normally until TS-lll is made which opens contacts R44 to de-energize relay R-6 causing loss of power to the system through opening of contacts Rt3.

Direct current blocking diodes D1 through D-10 are provided in the circuitry of FIGURE 16 to prevent current from flowing through the common solenoid line upon closure of any of the TS switches during movement of the wiper for selective loading of the turret.

A jumper 307 is provided in series in the circuitry to relay R-l, the relay which energizes the spare setting sequence by actuation through switch 345. The jumper is in an otherwise conventional disconnect plug provided in the bowlers console for putting the keyboard controls in the circuit. The purpose of the jumper is to prevent pin jams if the cnosole is unplugged while the turret is receiving pins. Accordingly, when the console is unplugged, the jumper is also thereby disconnected and power is lost to relay R1, causing contacts Rl-l and R1-2 to close energizing relay R2 (via R62, R63 and R4-3). The turret then continues indexing without receiving pins until it reaches the #5 pin position, whereupon relay R3 is closed through Rl-2 and TS5. Contacts R3-1 are thereby opened releasing the turret index and tripping the spider. Then TS-11 is closed which shuts off the system.
